钛合金板材是一种高模量弹塑性材料,在冷成形加工的过程中,回弹控制难度较大.金属板材的冷成形加工过程,实际涵盖了多种冷成形加工工况.就板材冷成形加工过程中遇到的各种工况进行梳理分析,归纳为若干典型的工况,针对不同的冷成形加工工艺所含盖的典型工况,对高模量弹塑性板材在冷成形加工脱模后的初始回弹问题,进行了精细的分析,并提出了高精度的解析解.从而,在理论上为诸如钛合金之类的高模量弹塑性板材的冷成形加工,冷成形模具设计,及其冷成形加工工艺的工序优化,提供参考依据.
Titanium alloy sheet is a kind of high modulus elastic-plastic material, it is difficult to control springback during cold forming process.Cold forming process of sheet metal actually covers many kinds of cold forming working conditions. Forming process encountered a variety of conditions combing analysis, summarized as a number of typical conditions, for different cold forming process covered by the typical conditions, the high modulus elastic plate in the cold forming process off After the mold initial rebound problem, carried out a detailed analysis, and put forward a high-precision analytical solution.Therefore, in theory, such as titanium alloy, such as high modulus elastic plate cold forming, cold forming die design , And its cold forming process optimization process to provide a reference.
